The Rev. Peter A. Seiler Jr., Interim Pastor

Consistory called the Rev. Peter A. Seiler Jr. to be Emmanuel’s Intentional Interim Pastor beginning September 1, 2020. Reverend Seiler retired from the United Methodist Church after 32 years and comes to us from Zion UCC in downtown York, where he has served as part-time pastor for five years.

Reverend Seiler has diverse experience from a variety of settings throughout his career including pastoral leadership at several churches, as a college chaplain, as a resident life administrator at Normandie Ridge senior living community, and as a rehabilitation specialist and counselor with Geisinger Health Systems.

While at a church in the York area, he helped develop an after school program for handicapped children, which led organizers to offering a week-long church camp and weekend retreats for older disabled youth. He also worked with the Boy Scouts affiliated with that church to create a program to help handicapped boys move through the ranks of scouting.

Reverend Seiler was ordained by the United Methodist Church, as a deacon in 1973 and as an elder in 1978, retiring from full-time active service in 2008.

Reverend Seiler earned an associate’s degree at Harrisburg Area Community College, a bachelor’s degree at Messiah College in Grantham, and a master’s degree at Wesley Theological Seminary in Washington, D.C. Continuing education included additional studies at Lancaster Theological Seminary and he completed interim ministry training through the Interim Ministry Network of Catonsville, Md.

He lives in Springettsbury Township, York County, with his wife, the Rev. Katherine Seiler.

Jamie BrownChoir Director

Jamie Brown found joy in most aspects of music coursework at York College—music theory, pedagogy, music history, instrumental and  choral conducting and music analysis—but conducting became her passion. Building a career in the classroom beginning in 2002, Jamie has experienced challenge and success. As an instrumental and vocal music teacher in Carroll County (Md.) Public Schools, Jamie has worked with different ages and grade levels of students—elementary, middle and high school. Currently a music teacher at Northwest Middle School in Taneytown, Md., Jamie is often reminded of what it takes to "grow a musician." She values her role in facilitating growth and she gives ownership in the final performance. Jamie likes the feeling of producing music from notes on paper—bringing voices together in harmony to make full sounds. In December, Jamie directs the community orchestra for the Annual Carol Sing at Emmanuel. In March 2012, she was guest conductor of the Hanover Symphony Orchestra for "A Night at the Carnival."  In June 2014, she conducted the choir at the Penn Central Conference annual meeting in Selinsgrove, Pa.
